requirements.txt

# Pinned to the versions this codebase is actually tested against (see
# CONTRIBUTING.md). Range = "current version, up to the next breaking
# boundary" - the next major for a stable (>=1.0) package, the next minor
# for a 0.x package (0.x minor bumps are semver's equivalent of a major).
#
# playwright and duckduckgo_search are pinned tighter (patch-only): playwright
# ships in lockstep with a specific browser revision (a version mismatch is a
# real, previously-hit failure mode - see tests/conftest.py's fallback
# executable_path logic), and duckduckgo_search has a history of breaking
# changes between versions.
#
# To bump a dependency: update the pin here, run `pytest`, and if you touch
# playwright specifically, re-run the full suite including
# tests/test_serp_playwright.py (it drives a real browser).
